     on any occasion, Reserves actually received are insufficient to pay for the
     corresponding Reserve Task, the shortfall shall be for the account of the
     Lessee and may not be carried forward or made the subject of any further
     claim for payment.

          3.6.3.  [INTENTIONALLY OMITTED]

          3.6.4.  Reserves shall be and remain the property of the Lessor until
     disbursed. Except as expressly set forth in Section 3.7 below, all
     undisbursed Reserves, upon Expire, shall be retained by Lessor as
     additional Rent for the Aircraft. Lessor shall be under no obligation to
     segregate Reserves, and may mingle Reserves with other funds.

          3.6.5.  Lessor Contribution for Reserve Tasks.  Only for the first
                  -------------------------------------
     scheduled overhaul for each Engine during the Term provided the build
     standard for such Engine overhaul does not exceed 6,000 hours/cycles), for
     the first auxiliary power unit overhaul

                                 Page 10 of 56

<PAGE>

     during the Term, and for the first landing gear overhaul during the Term,
     the Lessor shall reimburse Lessee for a fraction of the cost to Lessee for
     each such Reserve Task, the numerator of which fraction shall be the time
     since such overhaul on the Delivery Date and the denominator of which
     fraction shall be the time since overhaul when such Reserve Task is
     occasioned.

     3.7 Purchase Option. Provided no Default has occurred and is continuing,
         ---------------
the Lessee may purchase (i) the Aircraft, together with (ii) any undisbursed
Reserves less any Lessor contribution for Reserve Tasks pursuant to Section
3.6.5 above (the "Sold Reserves") on the following terms and conditions. The
Lessee may purchase the Aircraft together with the Sold Reserves at the end of
the twenty-fourth month of the Term for a purchase price of US$2,750,000, or at
the end of the thirty-sixth month of the Term for a purchase price of
US$2,450,000. To purchase the Aircraft together with the Sold Reserves at either
time, the Lessee must first provide the Lessor with written notice of its
irrevocable election to purchase no less than ninety days prior to the purchase
date. Any sale shall be "AS-IS," and Lessee shall be responsible for and
indemnify Lessor from any sales or use taxes. Upon such sale, the Lease shall
terminate, and Lessor shall return to Lessee the Security Deposit.

                  ------------------------------------------------------------
     Lessee will preserve and maintain its corporate existence and such of its
     licenses and franchises in any jurisdiction where failure to obtain such
     licensing or qualification would have a material adverse effect upon
     Lessee. The Lessee shall not consolidate or merge with or into any other
     corporation or sell, convey, transfer, lease or otherwise dispose of,
     whether in one transaction or a series of related transactions, all or
     substantially all of its assets. Lessee shall not (A) voluntarily suspend
     its operations; or (B) voluntarily or involuntarily permit to be revoked,
     canceled or otherwise terminated all or substantially all of the

     and operations of Lessee or the free and continued use and exercise
     thereof.

          4.4.3.  Maintenance of Consents and Approvals. The Lessee shall obtain
                  -------------------------------------
     or cause to be obtained, maintain in full force and effect and comply in

     on, or in connection with, every consent, license, authorization, approval,
     filing and registration obtained or effected in connection with this Lease
     and the Operative Documents, or which may from time to time be necessary
     under Applicable Law for the continued due performance of all obligations
     of the Lessee under this Lease, including without limitation qualifications
     to operate the Aircraft in accordance with Aviation Law, and under the
     other Operative Documents. Where it is required of Lessee under Applicable
     Law with respect to this Lease or under any Operative Document, consent,
     approval, sanction, to stamp, file, register or attend to any act, matter
     or thing, Lessee will do so promptly and within any applicable prescribed
     time period in respect thereof.

          4.4.4.  Change of Locale. Lessee will promptly advise Lessor of any
                  ----------------
     change in its principal place of business or chief executive office if
     there is more than one place of business.

          4.4.5.  Financial Information and Reports. The Lessee shall provide

     by independent public auditors, and (ii) within 45 days after the end
     thereof their respective quarterly financial statements certified as to
     their correctness by their respective duly authorized chief financial
     officer, together with a certificate signed by the Lessee's duly authorized
     chief executive officer to the effect that, based upon due inquiry and
     investigation, during such financial quarter no Event of Default occurred.

     December 31.

          4.4.6.  Evidence of Legal Authority to Lease and Operate the Aircraft.
                  --------------------------------------------------------------
     No later than January 31, 1996, the Lessee shall have obtained all
     licenses, permits and approvals required with respect to the Aircraft by
     the Aviation Authority or Applicable Law for the lease of the Aircraft, and
     for the commercial operation thereof by the Lessee, and Lessee shall
     provide Lessor with certified copies of such; provided, however, that if
     Lessee is unable to obtain the requisite approvals by such date despite its
     diligent efforts to do so, such date shall be extended, subject to Lessor's
     consent not to be unreasonably withheld.

     4.5.  Lessor's Covenant of Quiet Enjoyment. The Lessor agrees that, so long
           ------------------------------------
as no Event of Default shall have occurred and be continuing, neither the
Lessor, any Lender, the Beneficiaries, nor anyone validly claiming through or
under any of them will take (or fail to take) any action, the taking (or failure
to take) of which causes interference with the Lessee's rights hereunder or its
peaceful and quiet use, operation and possession of the Aircraft under this
Lease. Should such interference occur, Lessor shall promptly eliminate the cause
thereof, upon written notice from Lessee.

          SECTION 5. Operation, Maintenance, Possession
                     ----------------------------------

     5.1.  Title. Title to the Aircraft shall remain vested in Lessor.
           -----

     5.2.  Operation. Lessee agrees not to operate the Aircraft unless the
           ---------
Aircraft is covered by insurance as required by the provisions of Section 10
hereof or contrary to the terms of such insurance. Lessee agrees not to operate
the Aircraft except in a passenger configuration, in commercial or other
operations for which Lessee is duly authorized by the Aviation Authority. Lessee
will not permit the Airframe, an Engine or Appliance to be maintained, used or
operated during the Term in violation of any Applicable Law, or contrary to any
manufacturer's operating manuals or instructions, provided that Lessee will not
knowingly allow passengers or cargo customers to transport illegal drugs on the
Aircraft. Lessee shall pay all costs incurred in the operation of the Aircraft,
including but not limited to flight crews, cabin personnel, fuel, oil,
lubricants, maintenance, insurance, landing and navigation fees, airport
charges, passenger service and any and all other expenses of any kind or nature,
arising directly or indirectly in connection with or related to the use,
movement and operation of the Aircraft by Lessee during the Term. The
obligations of Lessee under this provision shall survive the end of the Term.

                                 Page 16 0f 56
<PAGE>

     5.3.  Maintenance in General. Lessee, at its own cost and expense (except
           ----------------------
as expressly otherwise provided in Sections 3.6.5 and 5.5), shall (i) service,
repair, maintain and overhaul the Airframe, each Engine, and each Appliance so
as to keep the same in as good operating condition as when delivered to Lessee
hereunder, and in such operating condition as may be necessary to enable the
airworthiness certification of the Aircraft to be maintained in good standing at
all times under Aviation Law, and (ii) at a minimum, give the Aircraft the same
level of attention and maintenance as the Lessee affords to the other Boeing
727-200 aircraft in its fleet, including Airworthiness Directive compliance and
level of incorporation, repairs, cleanliness, and correction of items of a
cosmetic nature (such as hail damage), except where the terms of this Lease
dictate other standards (provided, however, that lessee shall not be required to
hushkit the Aircraft); and (iii) maintain the Aircraft in compliance with the
requirements of the Airframe manufacturer's aging aircraft and corrosion control
program document and supplemental inspection document as periodically revised.
Included within the obligation of maintenance and repair is the obligation and
affirmative undertaking by Lessee to replace from time to time all worn or
defective Parts, to the extent required to cause the Aircraft to be in an
airworthy condition in all respects, and covered by an effective commercial
passenger transport category certificate of airworthiness at all times except
during those periods when the Aircraft is undergoing maintenance or repairs as
required by this Lease. The "build standard" applicable to all Engine shop
visits shall be 6,000 hours with regard to both exhaust gas temperature and Life
Limited Components. Excepting only "AOG" situations, selection of a Maintenance
Provider shall be subject to Lessor's prior written approval, such approval not
to be unreasonably withheld. All maintenance (other than routine flight line
maintenance) shall be performed by the manufacturer or the Maintenance Provider
(excepting "AOG" situations) in accordance with the Approved Maintenance
Program. If any significant changes (including without limitation, time limit
changes) shall be made to such Approved Maintenance Program, a copy of such
proposed changes shall be delivered to Lessor for its prior written approval,
such approval not to be unreasonably withheld, before such change is submitted
to the Aviation Authority for approval.

     5.4.  Parts.
           -----

           5.4.1.  Unless the Airframe, an Engine or an Appliance has suffered
     an Event of Loss, Lessee, at its own cost and expense, will during the Term
     promptly replace all Parts that may from time to time become worn out,
     lost, stolen, destroyed, seized, confiscated, damaged beyond repair or
     permanently rendered unfit for use for any reason whatsoever. In addition,
     in the ordinary course of maintenance, service, repair, overhaul or
     testing, Lessee may remove any Parts, whether or not worn out, lost,
     stolen, destroyed, seized, confiscated, damaged beyond repair or
     permanently rendered unfit for use, provided that Lessee shall replace such
     Parts as promptly as practicable with replacement Parts. All replacement
     Parts shall be free and clear of all Liens except Permitted Liens and shall
     be in as good operating condition as, and shall have a value and utility at
     least equal to, the Parts replaced assuming such replaced Parts were in the
     condition and repair required to be maintained by the terms hereof.

                                 Page 17 of 56
<PAGE>

          5.4.2.  All Parts at any time removed from the Airframe, an Engine or
     an Appliance shall remain the property of Lessor and subject to this Lease,
     no matter where located, until such time as such Parts shall be replaced by
     Parts that have been incorporated or installed in or attached to such
     Airframe, Engine, or Appliance and that meet the requirements for
     replacement Parts specified in this Section 5. Immediately upon any
     replacement Part becoming incorporated or installed in or attached to such
     Airframe, Engine, or Appliance, without further act, (i) title to such
     replacement Part shall thereupon vest in Lessor; (ii) such replacement Part
     shall become subject to this Lease and be deemed part of such Airframe,
     Engine, or Appliance, as the case may be, for all purposes hereof to the
     same extent as the Parts originally incorporated or installed in or
     attached to such Airframe or Engine or Appliance; and (iii) title to the
     replaced Part shall thereupon vest in Lessee, free and clear of all rights
     of Lessor and shall no longer be deemed a Part hereunder.

     5.5.  Airworthiness Directives. Except as expressly provided below, Lessee
           ------------------------
agrees to comply with all Airworthiness Directives which become due during the
Term.  All Airworthiness Directives shall be accomplished in strict compliance
with all issuing agency's specific instructions. Lessee shall comply with all
Airworthiness Directives at its sole cost and expense up to US$25,000 per any
one Airworthiness Directive. In the event that the cost of incorporating any
terminating Airworthiness Directive (including parts, labor, and materials, but
excluding any profit to Lessee) exceeds US$25,000 per any one Airworthiness
Directive, the amount of the excess to be borne by the Lessor shall be
calculated in accordance with the following formula:


                            1 - (N-M) x (C-25,000)
                                -----
                                  T

where "N" equals the total duration of the Term in months; "M" represents the
month of the Term in which the modification is completed; "C" represents the
total actual cost of labor, parts, and materials for the modification; and "T"
equals the actual useful life of the modification in months, not to extend
beyond December 31, 1999. If the Lessee's cost of complying with any one
Airworthiness Directive that must be accomplished during the Term exceeds One
Hundred Thousand Dollars (US$100,000) in any individual case, then Lessee may,
by written notice to Lessor, elect not to pay any portion of the cost of
complying with such Airworthiness Directive costing in excess of US$100,000, in
which event Lessor shall have the right to comply with the Airworthiness
Directive at its own expense, or by written notice to the Lessee within 15 days
following receipt of such notice from Lessee, may advise Lessee that Lessor
shall not perform such Airworthiness Directive (the "Excepted AD"), in which
case the Lease shall terminate, effective upon the earlier of the end of the
Term or the final compliance date for the Excepted AD, whereupon the Lessee
shall return the Aircraft to the Lessor in accordance with the provisions of
Section 6 hereof, excepting only (i) the Excepted AD, and (ii) the C Check
required by Section 6.5.1.

     5.6. Service Bulletins. Lessee agrees, at its sole cost and expense, to
          -----------------
incorporate into the Aircraft all those Airframe, Engine, and Appliance
manufacturer and other vendor service bulletins which Lessee adopts and
incorporates during the Term on the rest of the B727-200 aircraft in its fleet.
The Aircraft, with respect to the rest of the B727-200 aircraft in Lessee's
fleet, shall not be discriminated against in service bulletin compliance or
other maintenance matters.

     5.7. Modifications.
          -------------

          5.7.1.  Lessee, at its own expense, shall make such alterations and
     modifications in and additions to the Airframe or any Engine or Appliance
     as may be required to be made from time to time by Aviation Law during the
     Term regardless upon whom such requirements are, by their terms, nominally
     imposed, including, without limitation, any modifications required to
     enable the Aircraft to comply with environmental, noise, air pollution, and
     other standards ("Required Modifications"); provided, however, that Lessee
     shall not be required to hushkit the Aircraft.

          5.7.2.  Lessee shall not, without Lessor's prior written consent, make
     any major modifications, alterations or additions (collectively, "Optional
     Modifications") to the Aircraft. For purposes of this Section 5, the term
     Optional Modifications shall include, but shall not be limited to, (i)
     changes to the Aircraft structure or performance, (ii) changes which could
     adversely affect spare parts, interchangeability or replaceability, and
     shall exclude Required Modifications.

          5.7.3. NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, NO
     OPTIONAL MODIFICATION SHALL BE MADE WHICH HAS THE EFFECT OF DECREASING THE
     UTILITY OR VALUE OF THE AIRCRAFT OR ADVERSELY AFFECTS ITS AIRWORTHINESS OR
     USE FOR TRANSPORTING PASSENGERS IN COMMERCIAL SERVICE.

          5.7.4. All Optional Modifications, except as otherwise provided
     herein, shall be accomplished by Lessee at its own expense. Lessee shall
     provide advance copies of all drawings and data to be used by Lessee in
     accomplishing such Optional Modifications for Lessor's approval prior to
     such work. In the event Lessor does not consent to certain Optional
     Modifications to the Aircraft desired by Lessee, Lessor may give its
     qualified consent in writing to Lessee to accomplish such modifications
     which are unacceptable to Lessor on the condition that Lessee agrees to
     remove all such unacceptable modifications accomplished by Lessee and to
     reconstruct the modified areas to their original configuration in a good
     and workmanlike manner prior to return of the Aircraft to Lessor. In the
     event of Lessor's granting such qualified consent in writing, Lessee shall,
     at Lessee's sole expense, accomplish all such Optional Modifications,
     removal of such modifications and required reconstruction necessary to
     return the Aircraft to Lessor in its original configuration at the end of
     the Term. Lessor hereby consents to the following Optional Modifications,
     and agrees that such Optional Modifications may be

     system, provided that wiring therefor shall become an accession to the
     Aircraft owned by Lessor; (2) overwater emergency equipment supplied by
     Lessee; (3) an HF radio system supplied by Lessee; and (4) ACARS supplied
     by Lessee.

     5.8. Reports. Lessee shall furnish to Lessor the following reports on a
          -------
monthly basis: (i) the hours and cycles operated by the Airframe; and (ii) the
hours and cycles operated by each of the Engines (noting their location). Lessee
shall furnish to Lessor the following reports on a quarterly basis: (iii)
scheduled and unscheduled Engine and Appliance changes; (iv) damage reports; (v)
a list of those service bulletins, Airworthiness Directives and engineering
modifications issued during such quarter and applicable to the Aircraft, whether
or not incorporated on the Aircraft; (vi) copies of any written communications
with manufacturers with respect to defects or malfunctions of the Aircraft or
such other matters; and (vii) C Check, D Check, and Engine shop visit scheduled

significant theft or vandalism, extended periods of Aircraft grounding for
cause, and insured occurrences as promptly as practicable.

     5.9. Right to Inspect. Lessor and its agents shall have the right to
          ----------------
inspect the Aircraft or the Aircraft Documents at any reasonable time, upon
giving Lessee reasonable notice, to ascertain the condition of the Aircraft and
to satisfy Lessor that the Aircraft is being properly repaired and maintained in
accordance with the requirements of this Lease. No such inspection shall
interfere with Lessee's business or operations. The cost of the inspection or
survey shall be paid by Lessee if the Aircraft, or any part thereof, is not in
the condition required by this Lease, but shall otherwise be paid by the Lessor.
All repairs which shall be shown by the inspection or survey to be required
shall be made at Lessee's expense in accordance with the Approved Maintenance
Program. All required repairs shall be performed as soon as practicable after
such inspection. In the event of a dispute between Lessor and Lessee as to the
proper performance by Lessee of the repairs required hereunder, the decision of
the manufacturer of the Airframe, Engines, Appliances, or Part(s) (as
applicable) shall control. Lessor shall have no duty to make any such inspection
and shall not incur any liability or obligation by reason of not making such
inspection.

     5.10. Damage and Repairs. All damage to the Aircraft shall be documented
           ------------------
and any repair to the Aircraft shall be documented and accomplished pursuant to
the applicable manufacturer's structural repair manual instructions and (where
applicable) the Approved Maintenance Program. Such repairs shall be permanent.
Repairs to the skin of the Aircraft shall be flush and not merely patched,
unless otherwise permitted or provided in the Airframe manufacturer structural
repair manual; provided that any such permitted patch shall be permanent and not
temporary. Lessee shall notify Lessor and the manufacturer of any repair to the
structure or skin of the Aircraft or any other repair costing in excess of One
Hundred Thousand Dollars (US$ 100,000) promptly after its being made; provided,
however, that Lessor shall have no liability to Lessee or third parties with
regard to such repair or the quality thereof and Lessee shall indemnify and hold
Lessor harmless with regard thereto. All technical and engineering data,
calculations, drawings, and documentation covering major repairs shall become

                                 Page 20 of 56
<PAGE>

a permanent part of the Aircraft Documents. Any disagreement between Lessor and
Lessee as to what constitutes a "major" repair or a "permanent" repair shall be
referred to the applicable manufacturer and the Aviation Authority.

     5.11. Aircraft Documents. Lessee, at its expense, will at all times

Authority with respect to the Aircraft, including without limitation shop
records detailing service checks, inspections, tests, repairs, or overhauls. All
documentation of any type referred to in the preceding sentence is herein
individually and collectively referred to as the "Aircraft Documents." Records
produced by electronic data processing or other automated means are not
acceptable, except as summary documents accompanied by original, or manual,
records, unless specifically approved by the Lessor in writing. Aircraft
Documents pertaining to maintenance shall contain verification of accomplishment
and quality assurance by actual identifiable signature. All Aircraft Documents
shall be the property of the Lessor. All Aircraft Documents shall be stored by
Lessee during the Term at a secure facility, and Lessee shall notify Lessor in
writing of the location of such facility. All Aircraft Documents will be at all
times kept current and up to date in order to facilitate Lessor's ability to
inspect periodically the Aircraft, monitor the maintenance of the Aircraft
during the Term and to facilitate the sale or re-lease of the Aircraft to a
third party at the end of the Term. The Lessee shall retain a revision service
for all Airframe, Engine, Appliance and Part manufacturer's manuals and
documentation, and the Aircraft Documents shall at all times contain the latest
issued revisions and reflect the current configuration and status of the
Airframe, Engines, Appliances, and Parts.

                --------
     possible with a Part which has a value and utility at least equal to the
     Part being replaced and is owned by the Lessee free and clear of all Liens
     except Permitted Liens; and any such replacement Part shall thereby become
     subject to this Lease without necessity of further act; provided, however,
                                                             --------
     that any Part removed from the Airframe, an Engine, or an Appliance for
     such purpose shall remain subject to this Lease until replaced by a

     aircraft maintenance procedures of any sublessee shall be equivalent to
     those of the Lessee; (v) the Lessee shall assign any such sublease to the
     Lessor as security for Lessee's obligations under this Lease, provided that
     so long as no Event of Default shall have occurred and be continuing, (A)
     the Lessee, to the exclusion of the Lessor, may (in the name of the Lessor
     or otherwise) exercise all rights and powers, and have all benefits, of the
     sublessor under any such sublease, including, without limitation, the right
     to collect and retain for the Lessee's own account all rent and other
     payments due from the sublessee thereunder, and (B) Lessor shall not,
     without the prior written consent of Lessee, amend, modify or terminate
     such sublease, (vi) any sublessee shall be solvent and not seeking

           ------
Section 9 below, and subject to any qualifications as may be set forth in a
Schedule 3 signed by both parties and attached to the executed Lease Supplement
and Receipt, on the last day of the Term or earlier Expiry (the "Return Date"),
all of the terms of this Section 6 shall apply and the Lessee shall return the
Aircraft to the Lessor by delivering the same, at the Lessee's own risk and
expense, to Marana, Arizona, or such other place as may be mutually agreed upon
in writing by the Lessor and Lessee (the "Return Location"), fully equipped with
all Engines installed thereon. The Aircraft at the time of its return shall be
in the condition set forth in this Section 6 and shall be free and clear of all
Liens other than Lessor Liens; provided, however that if on the Return Date the
Aircraft is not in Lessee's possession as a result of a breach by Lessor of the
covenant set forth in Section 4.5 hereof, the aircraft shall be deemed
redelivered to Lessor wherever then located and any taxes or other costs and
expenses associated with delivery at such location shall be for the account of
Lessor. At the time of acceptance of return of the Aircraft to Lessor,

                                 Page 23 of 56
<PAGE>

Lessor and Lessee shall execute an Aircraft Return Receipt and Lease Termination
in the form attached hereto as Exhibit B.

     6.2.  Lease Continues. In the event, for any cause, Lessee does not
           ---------------
return the Aircraft to Lessor on the last day of the Term or earlier Expiry in
the condition required hereunder, then all of the obligations of Lessee under
this Lease shall continue and such continued use shall not be considered a
renewal of the Term of this Lease or a waiver of any right of Lessee hereunder.
During such continued use, Rent shall continue to be paid by Lessee to Lessor
and the other performance and obligations of Lessee to Lessor shall continue
hereunder and the same shall be prorated at the rate of one thirtieth (1/30) of
the monthly installment of Basic Rent for each day until the Aircraft is
actually delivered to Lessor, and all other terms and conditions of this Lease
shall remain in full force and effect. Payment shall be made within five (5)
Business Days after presentation of Lessor's invoice and any failure to pay
shall constitute an Event of Default of Lessee.

     6.3.  Return of Engines and Appliances. In the event any engine or

appliance not owned by Lessor shall be returned with the Airframe, Lessee will,
at its own expense and concurrently with such return, furnish Lessor with a full
warranty bill of sale, in form and substance satisfactory to Lessor, with
respect to each such replacement engine or appliance and shall take such other
action as Lessor may reasonably request in order that such replacement engine or
appliance shall be duly and properly titled in Lessor. Upon passage of title to
Lessor such replacement engine or appliance shall be deemed to be an Engine or
Appliance for all purposes hereof and thereupon Lessor will transfer by bill of
sale to Lessee, without recourse or warranty except a warranty against Lessor's
Liens, all of Lessor's right, title and interest in and to an Engine or
Appliance not installed on such Airframe at the time of the return thereof.
Provided, however, that any replacement engine or appliance shall, in the
opinion of the Lessor, have a value and utility at least equal to (and be in as
good operating condition as) such Engine or Appliance replaced, assuming
compliance by the Lessee with all of the terms of this Lease with respect to
such Engine or Appliance.

     6.6.  Condition of Landing Gear.  Each main and nose landing gear component
           -------------------------
and each associated actuator and Part shall be clean, free of leaks and repaired
as necessary. All decals shall be in the English language, clean, secure, and
legible.

     6.7.  Condition of Auxiliary Power Unit ("APU"). Lessee will return the
           -----------------------------------------
Aircraft's installed APU in serviceable condition, in accordance with the
manufacturer's specifications. Any operational discrepancies of the APU shall be
corrected at Lessee's expense prior to the return of the Aircraft to Lessor.

     6.8.  Condition of Engines.  Each Engine shall meet both the Engine
           --------------------
manufacturer specifications and the Approved Maintenance Program parameters for
acceptable exhaust gas temperature margin, engine pressure ratio, and fuel flow
at maximum certificated rated thrust.

     6.9.  Historical Records: Trend Monitoring Data.  If the Engine historical
           -----------------------------------------
and maintenance records and/or trend monitoring data indicate a rate of
acceleration in performance deterioration of any installed Engine which is
higher than normal based on Lessee's maintenance experience in operating such
Engines, or if an Engine is "on watch," Lessee shall, prior to the Aircraft's
return, correct or cause to be corrected such conditions which are determined to
exceed the Engine manufacturer's maintenance manual tolerances or otherwise be
causing such performance deteriorations or "on watch" condition.

     6.10. Inspections.  The following inspections shall be conducted utilizing
           -----------
the standards and specifications of the applicable manufacturer maintenance
manual for the Airframe, Engines, Appliances, and component Parts thereof. Any
item or discrepancy noted during the inspections that is found to be non-
compliant with the tolerances and conditions of the applicable manufacturer
maintenance manual shall be classified as a condition of non-airworthiness and
shall be corrected or rectified by Lessee prior to return of the Aircraft.

           6.10.1.  The Aircraft (including the Aircraft Documents) shall be
     made available to Lessor for ground inspection by Lessor at Lessee's
     facilities where and while the C Check required by this Section 6 is being
     performed. Lessee shall open the areas of the Aircraft, including without
     limitation galleys, lavatories, and cargo pits, as determined by Lessor,
     and shall allow Lessor to accomplish its inspection in order to determine
     that the Aircraft (including the Aircraft Documents) is in the condition
     required by the provisions of this Section 6.

           6.10.2.  A full, videotaped borescope inspection of all Engine and
     APU sections in accordance with manufacturer specifications (including
     manufacturer service bulletins) shall be performed under the surveillance
     of Lessor at Lessee's expense at the time of the Aircraft's return to
     Lessor at the Return Location.

           6.10.3.  Lessee shall conduct an operational ground check in
     accordance with the requirements of the Approved Maintenance Program.

                                 Page 27 of 56
<PAGE>

           6.10.4.  The Aircraft shall be test flown by Lessee at Lessee's
     expense for not less than two (2) hours on a non-commercial flight, for the
     purpose of demonstrating to Lessor the airworthiness of the Aircraft and
     the proper functioning of all systems, equipment, and Appliances. Five (5)
     of Lessor's employees or representatives (or more if consented to by
     Lessee) may participate in such flight as observers. Lessee's pilot shall
     be in command of the Aircraft.  Such flight shall be flown using standard
     operational check flight procedures as specified by the Airframe
     manufacturer's flight functional acceptance procedure or operational test
     flight procedures to demonstrate full certificated performance without
     limitation.

     6.11. Acceptance.  Upon completion of the foregoing inspections and after
           ----------
Lessee has corrected the discrepancies as required to comply with this Section
6, the return of the Aircraft shall be accepted by Lessor's representatives at
the Return Location. At the time of acceptance of return of the Aircraft to
Lessor, Lessor and Lessee shall execute an Aircraft Return Receipt and Lease
Termination in the form attached hereto as Exhibit B.

     6.12. Discrepancy Correction: Financial Settlement. Any discrepancies found
           --------------------------------------------
during the inspections set forth in Section 6.10 above which are not corrected
by Lessee prior to return of the Aircraft to Lessor may be corrected by Lessor
or its designee after return of the Aircraft and Lessee shall reimburse Lessor
for all costs and expenses incurred by Lessor or its designee for accomplishing
such discrepancy corrections. Lessee shall pay Lessor for all such costs and
expenses incurred within ten (10) days after presentation of Lessor's invoice
therefor. Any late payments shall be subject to interest at the Overdue Payment
Rate. In the event that the time since overhaul or check for the Airframe, any
Engine, Appliance or component Part thereof on the Return Date is greater than
set forth above, Lessee shall pay Lessor a financial settlement to account for
the difference based upon (1) the then current interval between such overhaul,
check, or inspection prescribed by Lessee's Approved Maintenance Program and (2)
the then current cost to perform such overhaul or check established by averaging
the cost estimates for such overhaul or check by three Aviation Authority-
certified repair stations selected by Lessee and reasonably acceptable to
Lessor. Lessor shall not be obligated to compensate Lessee in the event that the
Aircraft is in better condition on the Return Date than required hereunder.

     6.13. Aircraft Documents.  Lessee shall return to Lessor, at the time the
           ------------------
Aircraft is returned to Lessor, all of the Aircraft Documents, updated and
maintained by Lessee through the date of return of the Aircraft. In the event of
missing, incomplete, mutilated, or otherwise unacceptable Aircraft Documents,
the Lessee shall, at its sole cost and expense, re-accomplish the tasks
necessary to produce such Aircraft Documents in accordance with the provisions
of Section 5.11.

     6.14. Service Bulletin Kits.  All vendors' and manufacturers' service
           ---------------------
bulletin kits ordered for the Aircraft but not installed therein shall be
returned with the Aircraft, as part of the Aircraft at the time of return, and
shall be loaded by lessee on board the Aircraft as cargo.

<PAGE>

     6.15. Lessee's Special Exterior Markings.  At the time of the return of the
           ----------------------------------
Aircraft, Lessee shall either remove or paint over exterior markings painted on
such Aircraft by Lessee and the area where such markings were removed or painted
over shall be refurbished by Lessee as necessary to blend in with the
surrounding surface. In the event that, notwithstanding Lessee's obligation to
do so, Lessee does not remove such markings, Lessor shall have no obligation to
remove such markings prior to the sale, lease, or other disposition of the
Aircraft by Lessor after its return; however, if Lessor elects to remove such
markings, Lessee shall pay Lessor's costs and expenses for such removal within
ten (10) days after presentation of Lessor's invoice therefor. Any late payments
shall be subject to interest at the Overdue Payment Rate.

     6.16. Disputes.  Any dispute between Lessee and Lessor regarding the
           --------
condition of the Aircraft arising under this Lease shall be referred to and be
determined by the Airframe, Engine, or Appliance manufacturer, provided this
subsection shall not be construed as requiring binding arbitration. Anything to
the contrary provided in this Section 6, (i) in the event that at the Return
Date Lessee shall not be in possession by reason of a breach by Lessor of the
covenant set forth in Section 4.5 herein, Lessee shall be deemed to be in full
compliance with the conditions set forth in this Section 6, assuming such
Aircraft was in the condition then required at the time of its removal from
Lessee's possession as a result of such breach; and (ii) Lessee shall not be
required to correct at return conditions existing at delivery and noted in
Schedule 3 to the Lease Supplement and Receipt.

           SECTION 7. Liens. The Lessee will not create or suffer to exist any
                      -----
Lien upon or with respect to the Aircraft, the Airframe, any Engine or any
Appliance, except for the rights of the Lessor and the Lessee hereunder and
Permitted Liens.

           SECTION 8. Taxes.
                      -----

     8.1.  Tax Indemnity.  The Lessee agrees to pay, and to indemnify each
           -------------
Indemnitee for all taxes, fees, levies, imposts, duties, charges and
withholdings of any nature (together with any and all fines, penalties,
additions to tax and/or interest thereon or computed by reference thereto)

government, governmental subdivision or other taxing authority of or in any
jurisdiction, or by any international organization, and which are imposed with
respect to or in connection with any of the following:

           8.1.1.  The Aircraft or any Engine or any part thereof or any
     interest therein;

     modification, overhaul, testing, storage, abandonment, repossession, or
     return of the Aircraft or any Engine or any part thereof or any interest
     therein;

           8.1.3.  The rentals, receipts or earnings arising from the Aircraft
     or any Engine or any part thereof or any interest therein;

                                 Page 29 of 56
<PAGE>

           8.1.4.  This Lease or any other Operative Document; any agreement or
     instrument executed in connection with or pursuant to any of the foregoing;
     any future amendment, supplement, waiver or consent requested by Lessee
     with respect to any thereof, or the execution, delivery, recording or
     performance of any thereof; or

           8.1.5.  Any payment made pursuant to this Lease or any other
     Operative Document;

provided, however, that the Lessee shall not be required by this paragraph (a)
--------
to indemnify an Indemnitee for any of the following:

           8.1.6.  Taxes in respect of net or gross income, profits, gains,
     capital or net worth imposed by the United States or any state or local
     governments therein;

           8.1.7.  Taxes which would not have arisen but for delay or failure by
     an Indemnitee in notifying the Lessee or in the filing of Tax Returns or
     payment of Taxes assessed on such Indemnitee, which delay or failure shall
     not have been consented to, caused by or requested by the Lessee;

           8.1.8.  Any Tax to the extent it results directly from any act or
     omission on the part of the Lessor which constitutes a breach by the Lessor
     of its express obligations to the Lessee under this Lease or any Operative
     Document or otherwise constitutes wilful misconduct or gross negligence on
     the part of the Lessor;

           8.1.9.  Any Taxes to the extent properly attributable to any time or
     period prior to the date of this Lease or after its Expiry;

           8.1.10. In the event that the Lessor assigns, transfers or encumbers
     in whole or in part its interest in the Aircraft or this Lease and/or the
     proceeds thereof, any Taxes if and to the extent that such Taxes exceed
     those which would have been imposed and in respect of which the Lessee
     would have been liable to indemnify the Lessor under this Lease had the
     Lessor not so assigned, transferred, or encumbered its interest;

           8.1.11. Any Taxes which are caused by or arise out of or as a
     consequence of a Lessor Lien;

           8.1.12. Any Taxes in respect of ownership not attributable to
     Lessee's acts or omissions under this Lease; or

           8.1.12. Any Taxes (including, without limitation, sales, value added
     or other transfer Taxes) which arise upon any sale, assignment, transfer or
     other disposition of the Aircraft or any interest therein by the Lessor or
     any other Indemnitee (or any sale, assignment, transfer or other
     disposition by an Indemnitee of any interest in another

                                 Page 30 of 56
<PAGE>

     Indemnitee), save where such sale, assignment, transfer or other
     disposition is caused by or results from an Event of Default.

If the Lessor becomes aware of any Taxes in respect of which the Lessee may be
required to make an indemnity or other payment pursuant to this Section 8.1, the
Lessor shall promptly notify the Lessee in writing accordingly. If reasonably
requested by the Lessee in writing, the Lessor shall, in good faith, diligently
contest (including pursuing all administrative appeals) in the name of the
Lessor or, if appropriate and requested by the Lessee, in the name of the Lessee
(and will permit the Lessee, if requested by the Lessee, to contest in the name
of the Lessee or the Lessor) the validity, applicability or amount of such Taxes
and shall (i) resist payment thereof if reasonably practicable; (ii) pay the
same only under protest, if protest is necessary or proper; and (iii) if payment
is made, seek a refund thereof in appropriate administrative or judicial
proceedings Provided that (aa) prior to any such action the Lessee shall have
            --------
agreed to indemnify the Lessor to the Lessor's reasonable satisfaction for all
costs and expenses which the Lessor may incur in connection with such contest,
including (without limitation) all reasonable legal and accountants' fees and
disbursements, and the amount of any interest or penalties which may be payable
as a result of the contest; and (bb) if the Lessor determines in its reasonable
discretion that such contest is to be initiated by the payment of (and the
claiming of a refund for) such Taxes, the Lessee shall have advanced to the
Lessor sufficient funds (on an interest-free basis and, if such advance
constitutes taxable income in the hands of the Lessor, on an after-tax basis) to
make such payment.

If the Lessor shall obtain a refund, rebate, credit or other relief in respect
of all or any part of any Taxes in respect of which the Lessee shall have made
payment pursuant to this Section 8.1, the Lessor shall, provided no Event of
Default shall have occurred and be continuing, promptly pay to the Lessee an
amount which is equal to the amount of the refund, rebate, credit or other
relief, plus any interest or other addition received on any refund, Provided
                                                                    --------
always that any such payment by the Lessor shall leave the Lessor in no more and
no less favorable a position that it would have been in had the Lessee not been
required to make any payment in respect of such Taxes.

Lessee will pay all Taxes imposed upon it, or upon its income or profits, or
upon any property belonging to it, prior to the date on which penalties attach
thereto and prior to the date on which any lawful claim, if not paid, would
become a Lien upon any of the material property of Lessee. The Expiry of this
Lease shall not limit or modify the obligations of the Lessee with respect to
any indemnities contained in this Lease.

     8.2.  Withholding. If the Lessee is required by Applicable Law to make any
           -----------
withholding from any amount payable by the Lessee to or for the benefit of an
Indemnitee pursuant to this Lease or any related agreement, then, subject only
to such payee or Indemnitee being a United States person, the Lessee shall (i)
pay such additional amount as may be necessary to make the net amount actually
received by the person entitled to receive the payment, after all withholdings,
equal to the amount such person would have received if no withholding had been
required, and (ii) as soon as practicable thereafter, deliver to the Indemnitee
a receipt or other

                                 Page 31 of 56
<PAGE>

document reasonably satisfactory to the Indemnitee evidencing the withholding
and the payment of the amount withheld to the relevant governmental authority.

           8.2.1.  If the Lessor receives the benefit of a Tax repayment, set-
     off, credit, allowance or deduction resulting from a payment which includes
     an additional amount paid by the Lessee under this Section 8.2 (or the
     Taxes deducted or withheld from such payment) it shall pay to the Lessee a
     sum equal to the value to the Lessor of such benefit (account being taken
     also of the value to the Lessor of any tax benefit arising by reason of
     such payment) as in the opinion of the Lessor's auditors will leave the
     Lessor (after such payment) in no more and no less favorable a position
     than it would have been if no additional amount had been required to be
     paid Provided always that:
          --------

                   8.2.1.1.  The Lessor's auditors shall determine in their sole
           discretion (acting in good faith) the amount of any such benefit and
           the date on which it is received;

                   8.2.1.2.  The Lessor shall have an absolute discretion as to
           the order and manner in which it claims tax credits, allowances and
           deductions available to it; and

                   8.2.1.3.  The Lessor shall not be obliged to disclose to the
           Lessee any information regarding its Tax affairs or Tax computations.

If and to the extent that the Lessor makes a payment to the Lessee on account of
a tax benefit and it subsequently transpires that the Lessor did not receive
such benefit, the Lessee shall pay to the Lessor such sum as the Lessor's
auditors may certify as being appropriate to restore the after-tax position of
the Lessor to that which it would have been if such tax benefit had been
received.

     8.3.  After-tax Payment.  Each indemnity pursuant to Section 15 or this
           -----------------
Section 8 shall be in an amount which, after taking into account all Taxes
required to be paid by the Indemnitee entitled to the indemnity as a result of
the receipt or accrual of the indemnity and any deductions, credits or other
benefits available to such Indemnitee in respect of such indemnity, shall be
equal to the total amount of the indemnity that the Lessee would be required to
pay if the Indemnitee were not subject to Taxes as a result of the receipt or
accrual of the indemnity.

           SECTION 9. Risk of Loss: Event of Loss: Requisition for Use.
                      ------------------------------------------------

     9.1.  Risk of Loss.  The Lessee will bear the entire risk of destruction,
           ------------
loss, theft, requisition of title, or use, confiscation, taking or damage of or
to the Aircraft from any cause, except only if arising during any period when
the Aircraft shall not be in Lessee's possession as a result of a breach by
Lessor of the covenant set forth in Section 4.5 hereof, during the period
commencing when the Lease Supplement and Receipt is executed and delivered by
Lessee

                                 Page 32 of 56
<PAGE>

and ending when the Aircraft Return Receipt and Lease Termination is executed
and delivered by Lessor.

     9.2.  Airframe Event of Loss. If an Event of Loss shall occur with respect
           ----------------------
to the Airframe, the Lessee will forthwith notify the Lessor thereof in writing
and will pay to the Lessor, in U.S. Dollars and in immediately available funds
(i) 60 days after the date of the occurrence of such Event of Loss, or (ii) the
date of receipt of insurance proceeds, whichever is earlier, an amount equal to
the Stipulated Loss Value of the Aircraft; provided, however, that if the date
                                           --------
such payment is made by the Lessee is not a Rent Payment Date, there shall be
deducted from the amount payable by the Lessee an amount equal to a pro rata
portion of the Basic Rent for the Aircraft computed on a daily basis from and
including the date such payment is made by the Lessee to but not including the
Rent Payment Date immediately following the date such payment is made by the
Lessee. In addition, the Lessee will pay in full when due, but without
duplication, the Basic Rent for the Aircraft payable on each Rent Payment Date
occurring prior to the date payment is made by the Lessee pursuant to the
immediately preceding sentence hereof. Upon payment in full by the Lessee of all
amounts referred to above in this Section 9.2, this Lease shall terminate and
the Lessor will transfer to Lessee or its insurers, as appropriate, title to the
Airframe and each Engine, without any recourse, representation or warranty on
the part of the Lessor except that the Airframe and Engines are free and clear
of Lessor Liens.

     9.3.  Engine Event of Loss. If an Event of Loss shall occur with respect to
           --------------------
an Engine when not installed on the Airframe, the Lessee will forthwith notify
the Lessor thereof in writing and will, as soon as reasonably practicable after
the occurrence of such Event of Loss, duly convey to the Lessor (or cause to be
conveyed to the Lessor), as replacement for such Engine, title to another engine
of the same make and model which shall be owned by the Lessee free of all Liens
other than Permitted Liens and shall have a value and utility at least equal to
(and be in as good operating condition as) such Engine immediately prior to such
Event of Loss, assuming compliance by the Lessee with all of the terms of this
Lease with respect to such Engine. At the time of such conveyance the Lessee
will (i) cause to be delivered to the Lessor a favorable opinion of counsel for
the Lessee reasonably acceptable to the Lessor to the effect that the Lessor has
acquired full title to such replacement engine free and clear of all Liens
except for Permitted Liens and that such replacement engine is duly subjected to
this Lease; (ii) cause a Lease Supplement and Receipt to be duly executed by
Lessee and to be filed for recording pursuant to the Aviation Law and (iii)
cause to be delivered to the Lessor evidence satisfactory to the Lessor as to
the due compliance by the Lessee with the insurance provisions of Section 10
hereof with respect to such replacement engine. Upon compliance by the Lessee
with the foregoing terms of this subsection, the Lessor will (A) transfer to
Lessee or its insurers title to the Engine so replaced without any recourse,
representation or warranty on the part of the Lessor except that such Engine is
free and clear of any of the Lessor Liens and (B) execute and deliver to the
Lessee a partial release, in recordable form, releasing such Engine from this
Lease. Such replacement engine shall thereupon constitute an "Engine" for all
purposes hereof. Lessee shall be entitled to retain or to be reimbursed by
Lessor the amount of insurance or condemnation proceeds, if any, received by
Lessor with respect to such replaced Engine.

                                 Page 33 of 56
<PAGE>

     9.4.  Requisition.  In the event of the requisition for use by the
           -----------
Government of the United States of the Airframe or any Engine during the Term,
Lessee shall promptly notify Lessor of such requisition and all Lessee's
obligations under this Lease with respect to the Airframe or such Engine shall
continue to the same extent as if such requisition had not occurred. If the
Airframe or such Engine shall not be returned by the Government of United States
prior to the end of the Term, Lessee obligations under this Lease shall continue
until the end of such requisition, including without limitation the obligations
to pay Rent and to return the Airframe or such Engine to Lessor in accordance
with the provisions of Section 6 promptly upon its return by the Government of
the United States. Provided no Event of Default has occurred and is continuing,
all payments received by Lessor or Lessee from the Government of the United
States for the use of the Airframe or such Engine during such requisition shall
be paid over to, or retained by, Lessee.

           SECTION 10. Insurance.  Throughout the Term the Lessee shall cause to
                       ---------
be obtained maintained and kept in full force and effect property and liability
insurance (the "Insurances") with respect to the Aircraft issued through brokers
and with underwriters reasonably satisfactory to the Lessor. Such Insurances
shall name the Lessor as an additional insured and loss payee for its interests
and shall otherwise comply with the insurance requirements set out in this
Section 10.

     10.1. Reports. On or before the Delivery Date, and not later than seven (7)
           -------
days prior to each renewal of the Insurances, the Lessee shall provide the
Lessor with evidence satisfactory to the Lessor that the Insurances are and will
continue in full force after the Delivery Date or the renewal date of the
Insurances (as the case may be) for such period as shall then be stipulated and
the Lessee shall produce to the Lessor upon request receipts in respect of
payment of the premiums required by the policies relating to the Insurances (or
installments thereof) or other evidence reasonably acceptable to the Lessor of
the payment thereof. In addition, the Lessee shall furnish or cause to be
furnished to the Lessor, as and when reasonably required by the Lessor, (i)
insurance certificates, and (ii) an opinion of a firm of independent insurance
brokers satisfactory to Lessor (the "Approved Broker") stating the opinion of
the Approved Broker that the insurance then carried and maintained on the
Aircraft complies with the terms hereof. If any material variation is made to
the terms of the Insurances, the Lessee shall forthwith give notice to the
Lessor of such variation and shall provide such further details in relation
thereto (excluding details relating to premiums) as the Lessor may reasonably
require. The Lessee shall pay or cause to be paid all additional premiums or
surcharges necessary in order to maintain in full force and effect the
Insurances.

     10.2  Lessor Maintaining Insurances. If the Insurances are not kept in full
           -----------------------------
force and effect the Lessor, without prejudice to any other rights it may have
on the occurrence of an Event of Default, shall be entitled (but not bound) to
pay the premiums due to or to take out and maintain new insurances of the types
and in the amounts herein provided and any sums so expended by the Lessor shall
become immediately due and payable to the Lessor by the Lessee together with
interest thereon from the date of expenditure by the Lessor until the date of
reimbursement thereof by the Lessee at the Overdue Rate. In addition, the Lessor
may at any

                                Page 34 of 56
<PAGE>

time while the Insurances are not maintained in full force and effect and if
such Insurances cannot be procured by the Lessor, as the case may be, require
the Aircraft to be grounded or, subject to the Aircraft being adequately
insured, require the Aircraft to proceed to and remain at an airport designated
by the Lessor until the provisions of this Section shall be fully complied with.

     10.3  Insurance Proceeds.  Until such time as the insurers are notified of
           ------------------
an Event of Default hereunder, all insurance proceeds in respect of repairable
damage to the Aircraft not amounting to an Event of Loss shall be payable by the
insurers directly to such party or parties as may be necessary to repair the
Aircraft unless otherwise agreed between the Lessor, the Lessee and the insurers
in accordance with Lloyd's Endorsement AVN67B and shall be applied to the cost
of restoration, repair or replacement of the Aircraft hereunder. To the extent

estimated cost of completing such restoration, repair or replacement, the Lessee
will pay or procure the payment of such deficiency. All insurance proceeds in
circumstances resulting from an Event of Loss or if the insurers have been

     agreed value basis and shall: (i) include, in the event of separate
     insurances being arranged to cover the "All Risk" hull insurance and the

third party liability, bodily injury and property damage, passenger legal

insurance which may be available to the Indemnitees; and (iv) not provide
coverage to the Indemnitees with respect to claims arising out of their legal
liability as manufacturer, repairer or servicing agent of the Aircraft or any

     10.6. Provisions Relating To All Insurances. The policies evidencing the
           -------------------------------------
Insurances with respect to the Aircraft required under Subsection 10.4 and 10.5
shall:

           10.6.1. specifically reference this Agreement and shall provide that
     the insurers agree that the coverage under the policies is extended (to the
     extent of the risks covered by the policies) to insure such Aircraft in
     accordance with the terms of this Agreement;

           10.6.2. provide for worldwide coverage (subject only to such
     exceptions in the War Risks and related insurance as are imposed by the
     insurers, provided that full war risks and related insurance must be in
     effect at all times for all areas into or over which the Aircraft may
     operate);

           10.6.3. provide that the Lessor has no operational interest in the
     Aircraft;

           10.6.4. provide that the Insurances shall not be invalidated, so far
     as concerns the Indemnitees by any act or omission (including
     misrepresentation and non-disclosure) by the Lessee or any other person
     which results in a breach of any term, condition or warranty of such
     Insurances provided that the Indemnitees have not caused, contributed to or
     knowingly condoned such act or omission;

           10.6.5. provide that the Lessor shall not be liable for any premiums
     in respect thereof, and that the insurers waive any right of set-off or
     counterclaim against the Lessor except in respect of outstanding premiums
     in respect of the Aircraft;

                                 Page 36 of 56
<PAGE>

           10.6.6. provide that upon payment of any loss or claim to or on
     behalf of an Indemnitee, the insurers shall to the extent and in respect of
     such payment be thereupon subrogated to all legal and equitable rights of
     the Indemnitees. At the expense of the insurers, such persons shall do all
     things reasonably necessary to assist the insurers to exercise such
     subrogated rights; and

           10.6.7. provide that the Insurances provided under such policy may
     only be cancelled or materially altered in a manner adverse to the
     interests of the Lessor by the giving of not less than thirty (30) days'
     notice in writing to the Lessor except that in the case of War Risks
     insurance for which seven (7) days' notice (or such lesser period as may be
     customarily available in respect of war risks or allied perils insurance)
     will be given or in the case of war between any of the five (5) great
     powers or nuclear peril for which termination is automatic. Lessee will
     cause the Approved Broker to advise Lessor in writing promptly of any
     default in the payment of any premium and of any other act of omission on
     the part of Lessee of which they have knowledge and which would in the
     Approved Broker's opinion invalidate or render unenforceable, in whole or
     in any material part, any insurance on the Aircraft.

           SECTION 11. The Lessor's Right to Perform for the Lessee. If the
                       --------------------------------------------
Lessee fails to make any payment required hereunder or fails to perform or
comply with any of its other agreements contained herein, the Lessor may make
such payment or perform or comply with such agreement, including, but not
limited to, the placement of insurance required by this Lease, and the amount of
such payment and the amount of its out-of-pocket costs and expenses incurred in

to time reasonably request, in order to more effectively carry out the intent
and purpose of this Lease and the other Operative Documents and to establish and
protect the Lessor's title to the Aircraft and its rights and remedies created
or intended to be created under this Lease and the other Operative Documents.

           SECTION 13. Events of Default. The following events shall constitute
                       -----------------

and at any time thereafter, so long as the Lessee shall not have remedied all

Applicable Law then in effect:

     14.1. Return and Repossession. Lessor may in writing demand the prompt
           -----------------------
return, and the Lessee hereby agrees that it shall return promptly, the Aircraft

accordance with all the provisions of, Section 6 as if the Aircraft were being
returned at the end of the Term, or the Lessor or the Lessor's agent, at its
option, may, but shall be under no obligation to, enter upon the premises where
all or any part of the Airframe or any Engine or Appliance is located and take
immediate possession of and remove the same by summary proceedings or otherwise,
all without liability accruing to the Lessor or the Lessor's agent for or by

Lessee to pay to the Lessor, and the Lessee shall pay to the Lessor, on the
payment date specified in such notice, as liquidated damages for loss of a
bargain and not as a penalty (in lieu of the Basic Rent for the Aircraft due on
Rent Payment Dates occurring on and after the payment date specified for payment
in such notice), any unpaid Basic Rent for the Aircraft due (or which would have
been due in the absence of the Expiry) prior to the payment date specified in
such notice, plus an amount equal to the present value (computed as of the
payment date specified in such notice and using 6%) of the total Basic Rents due
for what would have been the remainder of the Term in the absence of the Expiry
("Liquidated Rental") (together with interest on all amounts payable by the
Lessee under this subsection 14.3 at the Overdue Payment Rate from such
specified payment date until the date of actual payment); and upon such payment
of Liquidated Rental and the payment of all other Rent then due hereunder,
Lessor shall

                                 Page 39 of 56
<PAGE>

proceed to exercise its best efforts to lease the Aircraft for what would have
been the remainder of the Term in the absence of Expiry and shall pay over to
Lessee an amount equal to the present value of the rents due for the remainder

costs and expenses whatsoever incurred by Lessor in connection therewith and all
other amounts which may become payable to Lessor) up to the amount of Liquidated
Rental actually paid.

     14.4. Cancellation, Termination, and Rescission. The Lessor may cancel,
           -----------------------------------------
terminate, or rescind this Lease, or may exercise any other right or remedy
which may be available to it under Applicable Law or proceed by court action to
enforce the terms hereof or to recover damage for the breach hereof, including
without limitation Lessee's agreement to lease the Aircraft for the Term and to
pay Rent.

     14.5. Other Remedies.  In addition, the Lessee shall be liable, except as
           --------------
otherwise provided above, for any and all unpaid Rent due hereunder before,
after or during the exercise of any of the foregoing remedies and for all legal
fees and other costs and expenses incurred by reason of the occurrence of any
Event of Default or the exercise of remedies with respect thereto, including all
costs and expenses incurred in connection with any retaking of the Aircraft or
in placing the Aircraft in the condition and airworthiness required by Sections
5 and 6. At any sale of the Aircraft pursuant to this Section 14 the Lessee may
bid for and purchase such property. No remedy referred to in this Section 14 is
intended to be exclusive, but each shall be cumulative and in addition to any
other remedy referred to above or otherwise available to the Lessor at law or in
equity, including without limitation the Uniform Commercial Code of the
Commonwealth of Massachusetts; and the exercise or beginning of exercise by the
Lessor of any one or more of such remedies shall not preclude the simultaneous
or later exercise by the Lessor of any or all of such other remedies. No express
or implied waiver by the Lessor of any Event of Default or Default shall in any
way be, or be construed to be, a waiver of any future or subsequent Event of
Default or Default. To the extent permitted by Applicable Law, the Lessee hereby
waives any rights now or hereafter conferred by statute or otherwise which may
require the Lessor to sell, lease or otherwise use the Aircraft in mitigation of
the Lessor's damages except as set forth in this Section 14 or which may
otherwise limit or modify any of the Lessor's rights or remedies under this
Section 14.

<PAGE>

           15.1.1.1. This Lease, any misrepresentation made by the Lessee under

           15.1.1.3. The Aircraft's condition or any discoverable or
     nondiscoverable defect in it arising from its design, testing, or
     construction; any article used in the Aircraft; or any maintenance, service
     or repair, whether or not the Aircraft is in the Lessee's possession and
     regardless of where the Aircraft is located; or

           15.1.1.4. Any transaction, approval, or document contemplated by this
     Lease.

           15.1.1.5. The foregoing indemnity shall not apply to (i) any Claim
     that constitutes a Permitted Lien, (ii) Claims for Taxes, it being agreed
     that Section 8 hereof represents Lessee's entire obligation with respect to
     Taxes, (iii) Claims attributable to the wilful misconduct of an
     Indemnitee; (iv) Claims attributable to any misrepresentation made by the
     Lessor under this Lease, or the breach of any representation, warranty, or
     covenant made by the Lessor under this Lease; or (v) Claims arising prior
     to the Delivery Date or subsequent to the Return Date; provided, however,
     that this Subsection 15.1.1.5 shall be construed only as a limitation on
     the indemnity set forth in this Section 15, and shall not be deemed a
     waiver by Lessor of any Claims available to Lessor at law or in equity.

     15.1.2. The Lessee waives and releases each Indemnitee from any Claims in
any way connected with injury to or death of the Lessee's personnel, loss or

           15.1.2.1. Result from or arise during the Term in any manner out of
     the leasing, condition, use or operation of the Aircraft; or

           15.1.2.2. Be caused during the Term by any defect in the Aircraft;
     its design, testing, or construction; any article used in the Aircraft; or
     any maintenance, service, or repair, whether or not the Aircraft is in the
     Lessee's possession and regardless of where the Aircraft is located, except
     to the extent that such Claim arises out of the breach by any Indemnitee of
     its obligations hereunder. The foregoing waiver and release shall not apply
     to any Claim arising out of the wilful misconduct of any Indemnitee.

     15.1.3. The indemnities described in this Section will continue in full
force and effect notwithstanding the expiration or other termination of this
Lease and are expressly made for the benefit of and will be enforceable by each
Indemnitee.

     15.2. Legal Fees and Expenses.  The Lessee agrees to pay the reasonable

assign, sell or encumber any interest of Lessor in the Aircraft or this Lease
and/or the proceeds hereof subject to the rights of Lessee under the provisions
of this Lease. To effect or facilitate any such assignment, sale or encumbrance,
Lessee agrees to provide such agreements, consents, conveyances or documents as
may be reasonably requested by Lessor, which shall include, without limitation,
a commercially standard estoppel certificate. The agreements, covenants,
obligations and liabilities contained herein including, but not limited to, all
obligations to pay Rent and indemnify each Indemnitee are made for the benefit
of each Indemnitee and their respective successors and assigns; provided,
however, that no assignment, sale or encumbrance shall in any manner adversely
affect Lessee's rights or increase the aggregate financial exposure under the
indemnity obligations of Lessee under this Lease or unreasonably increase any
other obligation, liability, cost, or expense, as compared to what such
indemnity obligations, or any other obligation, liability, cost or expense would
have been had such assignment, sale or encumbrance not occurred; provided,
however, that as a minimum level cooperation Lessee at its expense shall, if
requested by Lessor, (i) execute documents naming any Lender as an Indemnitee
hereunder; (ii) cause the Insurances to designate any Lender as a loss payee and
additional insured; (iv) provide notices to any Lender pursuant to Section 17
hereof; and (v) execute a reasonable consent to an assignment of this Lease to
such Lender. In the event any interest of the Lessor in the Aircraft or this
Lease and/or the proceeds therefrom is assigned, sold or encumbered by Lessor,
any assignee, transferee, mortgagee, or other secured party shall agree as a
condition precedent thereto, and shall furnish written evidence of such
agreement to Lessee, not to disturb or otherwise interfere with the rights of
Lessee under this Lease or the quiet enjoyment of Lessee of the Aircraft so long
as no Event or Default shall have occurred and be continuing; and provided,
further, that no such assignment, sale or encumbrance shall be to other than an
entity which shall be a United States citizen in accordance with Aviation Law.

the manufacturer of the Airframe or of any Engine or Appliance or anyone else
for any reason whatsoever (whether in connection with the transactions
contemplated hereby or in connection with any unrelated transaction), (ii) any
defect in the airworthiness, eligibility for registration, condition, design,
operation, or fitness for use of, or any damage to or loss or destruction of, or
any Lien upon, the Aircraft, or any interruption or cessation in the use or
possession thereof by the Lessee (iii) any insolvency, bankruptcy,
reorganization or similar proceedings by or against the Lessee, the Lessor or
any other person, (iv) the invalidity or unenforceability of this Lease or any

not similar to any of the foregoing. If for any reason whatsoever this Lease
shall be terminated in whole or in part by operation of Applicable Law the
Lessee nonetheless agrees to pay to the Lessor an amount equal to each Basic
Rent payment for the Aircraft at the time such payment would have become due and
payable in accordance with the terms hereof had this Lease not been so
terminated in whole or in part. The Lessee hereby waives, to the extent
permitted by Applicable Law, any and all rights which it may now have or which
at any time hereafter may be conferred upon it, by Applicable Law to terminate,
cancel, quit or surrender this Lease, or any obligation imposed on the Lessee by
this Lease. Nothing in this Section 18 shall be construed to preclude the
Lessee from bringing any suit at law or in equity against any person which it
would otherwise be entitled to bring for breach of any representation, warranty,
covenant or duty hereunder.

           SECTION 19. Governing Law.
                       -------------

     19.1. Consent to Jurisdiction.  Each of the Lessor and the Lessee
           -----------------------
irrevocably agrees that any legal suit, action or proceeding arising out of or
relating solely to this Lease or any other Operative Document, or any of the
transactions contemplated hereby or thereby or any document referred to herein
or therein, may be instituted in the state or Federal courts in the Commonwealth
of Massachusetts, and it hereby irrevocably waives, to the fullest extent
permitted by law, any objection which it may have now or hereafter to the laying
of the venue or the jurisdiction or the convenience of the forum of any such
legal suit, action or proceeding and irrevocably submits generally and
unconditionally to the jurisdiction of any such court but only in any such suit,
action or proceeding. Final judgment against the Lessee or the Lessor in any
suit shall be conclusive, and may be enforced in other jurisdictions by suit on
the judgment, a certified or true copy of which shall be conclusive evidence of
the fact and of the amount of any indebtedness or liability of the Lessee or the
Lessor, as the case may be, therein described; provided always that the
plaintiff may at its option bring suit, or institute other judicial proceedings,
against the Lessee or the Lessor, as

where the Lessee or the Lessor, as the case may be, or such assets may be found.

     19.2. Choice of Law.  THIS LEASE SHALL IN ALL RESPECTS BE GOVERNED BY, AND
           -------------
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS,
INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE.

           SECTION 20.  Miscellaneous. This Lease constitutes the entire
                        -------------
agreement of the parties. Any provision of this Lease which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibitions or unenforceability in
any jurisdiction shall not invalidate or render unenforceable such provision in
any other jurisdiction.

           This Lease shall constitute an agreement of lease, and nothing herein
shall be construed as conveying to the Lessee any right, title or interest in
the Aircraft except as a lessee only.

           This Lease, including all agreements, covenants, representations and
warranties, shall be binding upon and inure to the benefit of, and may be
enforced by, (1) Lessor and its agents, servants and personal representatives
and, to the extent permitted hereby, assigns and (2) Lessee and its agents,
servants, and personal representatives and, to the extent permitted hereby,
assigns. The section and subsection headings in this Lease are for convenience
of reference only and shall not modify, define, expand or limit any of the terms
or provisions hereof. This Lease may be executed by the parties hereto in
separate counterparts, each of which when so executed and delivered shall be an
original, but all such counterparts shall together constitute but one and the
same instrument. No term or provision of this Lease may be changed, waived,
discharged or terminated orally, but only by an instrument in writing signed by
the party against which the enforcement of the change, waiver, discharge or
termination is sought.

                          ---------------------------

                              GUARANTY AGREEMENT


     This Guaranty Agreement ("Guaranty") dated as of January 19, 1996, is made
by Columbia Sussex Corporation, a corporation organized under the laws of
Kentucky ("Guarantor").

                                  WITNESSETH:

     WHEREAS, FIRST SECURITY BANK OF UTAH, National Association, ("Lessor"), a
national banking association organized and existing under the laws of the United
States, not in its individual capacity but solely as owner trustee under that
certain Trust Agreement "AFG/Northwest Airlines 1989-4 Trust" dated as of
December 13, 1989, and Amended as of March 1, 1990, has agreed to enter into
that certain Aircraft Lease Agreement dated as of January 19, 1996 (the "Lease")
pursuant to which it is to lease the Aircraft defined therein to SUNWORLD
INTERNATIONAL AIRLINES, INC., a Kentucky corporation ("Lessee"), and

     WHEREAS, Lessor has agreed to enter into the Lease with Lessee but only if
Lessee's obligations under the Lease are guaranteed by Guarantor.

     NOW, THEREFORE, in consideration of the premises and in order to induce
Lessor, as requested by Guarantor, to enter into the Lease, Guarantor does
hereby represent, covenant and agree with Lessor as follows:

I.   GUARANTY OBLIGATIONS

     1.1  Guarantor hereby absolutely and unconditionally guarantees to Lessor,
the punctual and faithful payment and performance of all of the Liabilities (as
hereinafter defined) of Lessee to Lessor under the Lease (whether such
Liabilities are now existing or arise hereafter); and the strict performance and
observance by Lessee of all of the terms, covenants and conditions contained in
the Lease. As used herein, the term "Liabilities" includes, without limitation,
any and all Basic Rent, Supplemental Rent and undertakings of Lessee to Lessor
of every kind and description under the Lease (including, also, without
limitation, reasonable costs and expenses incurred by the Lessor in attempting
to collect or enforce any of the foregoing including reasonable attorneys' fees)
including interest on any such amounts accrued in each case from the due date
thereof to the date payment is received by Lessor provided, however, interest
                                                  --------- -------
due Lessor hereunder as Supplemental Rent shall not also be payable to Lessor a
second time because of the provisions of this sentence.

                                     -56-
<PAGE>

     1.2  This Guaranty is an absolute, unconditional and continuing guaranty of
the full and punctual payment and performance by Lessee of the Liabilities and
not of their collectibility only The liabilities and obligations of Guarantor
hereunder may be enforced without any suit or action against Lessee or any other
guarantor of any of the Liabilities, without regard or resort to any security or
other means of obtaining payment of the Liabilities which Lessor may now or
hereafter have or hold, and without the performance or occurrence of any other
condition or contingency whatsoever; provided, however, that the exercise or
attempted exercise, at any time or times, of any or all of such rights and
remedies as Lessor may have against Lessee, or with respect to any security for
liabilities or under any other guaranty of Liabilities shall not affect, reduce,
modify or impair, in any manner whatsoever, the liabilities and obligations of
the Guarantor hereunder, except and to the extent Lessor has received payment or
performance of such Liabilities of Lessee. Guarantor hereby unconditionally
waives to the fullest extent permitted by law (except to the extent specifically
provided in this Guaranty) demand, or notice of any nature. Payments by
Guarantor hereunder shall be unlimited in amount with respect to its guaranty of
the Liabilities, as defined above.

     1.3  Guarantor hereby waives any and all suretyship defenses and defenses
in the nature thereof; and agrees that enforcement of this Guaranty shall not be
affected, reduced, modified or impaired by any dealing by Lessor with Lessee or
anyone else who may now or hereafter become liable in any manner for any of the
Liabilities, in such manner as Lessor, in its sole discretion, may deem fit,
except to the extent that Lessor has waived or released in writing any
Liabilities and except and to the extent Lessor has received payment or
performance of such Liabilities by Lessee. If for any reason, Lessee has no
legal existence or is under no legal obligation to discharge any of the
Liabilities; or if, by operation of law or for any other reason, moneys included
in the Liabilities have become irrecoverable from Lessee, or if any security for
any of the Liabilities or if any other guaranty thereof is invalid, defective or
unenforceable, this Guaranty shall be binding upon Guarantor to the same extent
as if Guarantor were at all time primarily obligated on the Liabilities .

     1.4  No setoff, counterclaim, reduction or diminution of any Liabilities,
or any defense of any kind or nature, which Guarantor has or may have against
Lessee, shall be available hereunder to Guarantor against Lessor.

     1.5  This Guaranty shall remain in full force and effect regardless of any
payment hereunder or of any reduction in, or modification or alteration of the
Liabilities, until such time as

                                     -57-
<PAGE>

all Liabilities not waived or released by Lessor in writing and all liabilities
and obligations of Guarantor hereunder have been paid and performed in full.
Guarantor's obligations under this Guaranty shall be immediately extinguished
upon the full, complete and faithful performance by Lessee of all of its
Liabilities.  So long as this Guaranty remains in force, as aforesaid, Guarantor
will not, (x) by paying any sum recoverable hereunder (whether or not demanded
by the Lessor) or by any means or on any other ground, claim any set-off or
counterclaim against Lessee in respect of any liability of Guarantor to Lessee
or, (y) in bankruptcy or insolvency proceedings of any nature, prove in
competition with Lessor in respect of any payment hereunder or in any such
proceeding be entitled to have the benefit of any counterclaim or proof of claim
or dividend or payment by or on behalf of Lessee or the benefit of any other
security for any of the Liabilities which, now or hereafter, Lessor may hold or
in which it may have any share.  All payments by Guarantor hereunder shall be
made in lawful money of the United States of America in immediately available
funds and, so long as the person or entity entitled thereto is a United States
person within the meaning of the Internal Revenue Code, without any deduction or
withholding of any kind.

     1.6  Guarantor hereby confirms that this Guaranty shall remain in full
force and effect notwithstanding that:

          (a)  the obligations of the Lessee under the Lease are discharged,
               extinguished, terminated, rescinded, avoided or suspended
               (whether pursuant to any provision of the Lease or otherwise) by
               virtue of any breach on the part of the Lessee, under the
               doctrine of frustration, as a result of the liquidation of the
               Lessee or any action taken in such liquidation (for example, a
               disclaimer), except by payment or performance thereof; or

          (b)  subject to the provisions of the Lease, performance of the Lease
               by the Lessee becomes impossible or illegal,

and, in particular, the Lessor shall be entitled to recover under this Guaranty
in respect of any payment or obligation (including any obligation of paying
interest) which the Lessor would have received under the Lease but for the
occurrence of any of the circumstances described in subsections (a) or (b)
above.

     1.7  If the Lease is disclaimed in a liquidation of the Lessee:

          (a)  so long as any amounts or obligations then due from the Guarantor
               under this Guaranty remain unpaid or unperformed, as the case may
               be, the

                                     -58-
<PAGE>

               Guarantor shall not, in respect of any payment which it makes or
               any liability which it has, under this Guaranty or the Lease,
               claim any amount from the Lessee, make or enforce any security
               against any asset of the Lessee, or claim any set off against any
               sum from it to the Lessee; and

          (b)  the Guarantor shall not, in respect of such payment or liability,
               prove in the liquidation of the Lessee, except that, if the
               Guarantor shall have paid and/or performed all of its obligations
               then due hereunder, it shall be subrogated to all rights of
               Lessor against Lessee, and the Guarantor may, by exercise of that
               statutory right, prove for any loss or damage suffered by the
               Lessor, and otherwise as its interests may appear.

                              GUARANTY AGREEMENT

     This Guaranty Agreement ("Guaranty) dated as of January 19, 1996, is made
                                                             --
by Columbia Sussex Corporation a corporation organized under the laws of
Kentucky ("Guarantor").

                                 WITNESSETH :

     WHEREAS, FIRST SECURITY BANK OF UTAH, National Association, ("Lessor"), a
national banking association organized and existing under the laws of the United
States, not in its individual capacity but solely as owner trustee under that
certain Trust Agreement "AFG/Northwest Airlines 1989-4 Trust" dated as of
December 13, 1989, and Amended as of March 1, 1990, has agreed to enter into
that certain Aircraft Lease Agreement dated as of January 19, 1996 (the "Lease")
                                                          --
pursuant to which it is to lease the Aircraft defined therein to SUNWORLD
INTERNATIONAL AIRLINES, INC., a Kentucky corporation ("Lessee"), and

     WHEREAS, Lessor has agreed to enter into the Lease with Lessee but only if
Lessee's obligations under the Lease are guaranteed by Guarantor.

     NOW, THEREFORE, in consideration of the premises and in order to induce
Lessor, as requested by Guarantor, to enter into the Lease, Guarantor does
hereby represent, covenant and agree with Lessor as follows:

I.   GUARANTY OBLIGATIONS

     1.1  Guarantor hereby absolutely and unconditionally guarantees to Lessor,
the punctual and faithful payment and performance of all of the Liabilities (as
hereinafter defined) of Lessee to Lessor under the Lease (whether such
Liabilities are now existing or arise hereafter); and the strict performance and
observance by Lessee of all of the terms, covenants and conditions contained in
the Lease.  As used herein, the term "Liabilities" includes, without limitation,
any and all Basic Rent, Supplemental Rent and undertakings of Lessee to Lessor
of every kind and description under the Lease (including, also, without
limitation, reasonable costs and expenses incurred by the Lessor in attempting
to collect or enforce any of the foregoing including reasonable attorneys' fees)
including interest on any such amounts accrued in each case from the due date
thereof to the date payment is received by Lessor provided, however, interest
                                                  --------- -------
due Lessor hereunder as Supplemental Rent shall not also be payable to Lessor a
second time because of the provisions of this sentence.
<PAGE>

     1.2  This Guaranty is an absolute, unconditional and continuing guaranty of
the full and punctual payment and performance by Lessee of the Liabilities and
not of their collectibility only. The liabilities and obligations of Guarantor
hereunder may be enforced without any suit or action against Lessee or any other
guarantor of any of the Liabilities, without regard or resort to any security or
other means of obtaining payment of the Liabilities which Lessor may now or
hereafter have or hold, and without the performance or occurrence of any other
condition or contingency whatsoever; provided, however, that the exercise or
attempted exercise, at any time or times, of any or all of such rights and
remedies as Lessor may have against Lessee, or with respect to any security for
liabilities or under any other guaranty of Liabilities shall not affect, reduce,
modify or impair, in any manner whatsoever, the liabilities and obligations of
the Guarantor hereunder, except and to the extent Lessor has received payment or
performance of such Liabilities of Lessee. Guarantor hereby unconditionally
waives to the fullest extent permitted by law (except to the extent specifically
provided in this Guaranty) demand, or notice of any nature. Payments by
Guarantor hereunder shall be unlimited in amount with respect to its guaranty of
the Liabilities, as defined above.

     1.3  Guarantor hereby waives any and all suretyship defenses and defenses
in the nature thereof; and agrees that enforcement of this Guaranty shall not be
affected, reduced, modified or impaired by any dealing by Lessor with Lessee or
anyone else who may now or hereafter become liable in any manner for any of the
Liabilities, in such manner as Lessor, in its sole discretion, may deem fit,
except to the extent that Lessor has waived or released in writing any
Liabilities and except and to the extent Lessor has received payment or
performance of such Liabilities by Lessee. If for any reason, Lessee has no
legal existence or is under no legal obligation to discharge any of the
Liabilities; or if, by operation of law or for any other reason, moneys included
in the Liabilities have become irrecoverable from Lessee, or if any security for
any of the Liabilities or if any other guaranty thereof is invalid, defective or
unenforceable, this Guaranty shall be binding upon Guarantor to the same extent
as if Guarantor were at all time primarily obligated on the Liabilities.

     1.4  No setoff, counterclaim, reduction or diminution of any Liabilities,
or any defense of any kind or nature, which Guarantor has or may have against
Lessee, shall be available hereunder to Guarantor against Lessor.

     1.5  This Guaranty shall remain in full force and effect regardless of any
payment hereunder or of any reduction in, or modification or alteration of the
Liabilities, until such time as

                                      -2-
<PAGE>

all Liabilities not waived or released by Lessor in writing and all liabilities
and obligations of Guarantor hereunder have been paid and performed in full.
Guarantor's obligations under this Guaranty shall be immediately extinguished
upon the full, complete and faithful performance by Lessee of all of its
Liabilities. So long as this Guaranty remains in force, as aforesaid, Guarantor
will not, (x) by paying any sum recoverable hereunder (whether or not demanded
by the Lessor) or by any means or on any other ground, claim any set-off or
counterclaim against Lessee in respect of any liability of Guarantor to Lessee
or, (y) in bankruptcy or insolvency proceedings of any nature, prove in
competition with Lessor in respect of any payment hereunder or in any such
proceeding be entitled to have the benefit of any counterclaim or proof of claim
or dividend or payment by or on behalf of Lessee or the benefit of any other
security for any of the Liabilities which, now or hereafter, Lessor may hold or
in which it may have any share. All payments by Guarantor hereunder shall be
made in lawful money of the United States of America in immediately available
funds and, so long as the person or entity entitled thereto is a United States
person within the meaning of the Internal Revenue Code, without any deduction or
withholding of any kind.

     1.6  Guarantor hereby confirms that this Guaranty shall remain in full
force and effect notwithstanding that:

          (a)  the obligations of the Lessee under the Lease are discharged,
               extinguished, terminated, rescinded, avoided or suspended
               (whether pursuant to any provision of the Lease or otherwise) by
               virtue of any breach on the part of the Lessee, under the
               doctrine of frustration, as a result of the liquidation of the
               Lessee or any action taken in such liquidation (for example, a
               disclaimer), except by payment or performance thereof; or

          (b)  subject to the provisions of the Lease, performance of the Lease
               by the Lessee becomes impossible or illegal;

and, in particular, the Lessor shall be entitled to recover under this Guaranty
in respect of any payment or obligation (including any obligation of paying
interest) which the Lessor would have received under the Lease but for the
occurrence of any of the circumstances described in subsections (a) or (b)
above.

     1.7  If the Lease is disclaimed in a liquidation of the
Lessee :

          (a)  so long as any amounts or obligations then due from the Guarantor
               under this Guaranty remain unpaid or unperformed, as the case may
               be, the

                                      -3-
<PAGE>

               Guarantor shall not, in respect of any payment which it makes or
               any liability which it has, under this Guaranty or the Lease,
               claim any amount from the Lessee, make or enforce any security
               against any asset of the Lessee, or claim any set off against any
               sum from it to the Lessee; and

          (b)  the Guarantor shall not, in respect of such payment or liability,
               prove in the liquidation of the Lessee, except that, if the
               Guarantor shall have paid and/or performed all of its obligations
               then due hereunder, it shall be subrogated to all rights of
               Lessor against Lessee, and the Guarantor may, by exercise of that
               statutory right, prove for any loss or damage suffered by the
               Lessor, and otherwise as its interests may appear.
